When we are in love, we experience the effects of dopamine, a neurotransmitter from the pleasure and reward pathway. Dopamine is powerful and it can be wonderful, causing effects such as excitement, focus, and intense pleasure.

(I love how cute dopamine is. It looks like a little critter with ears or and alien with antenna.)

This keychain is a wonderful token for someone who increases your dopamine. It is sterling silver, including the keyring. The split ring keyring is about 1 inch in diameter and the dopamine molecule is a little over one inch long.

It comes packaged in a pretty gift box made of recycled materials and a little tag about dopamine.

Frequently asked questions about molecularmuse

I can make custom molecule jewelry, if the molecule will work in my style. Prices start around $150 and the process usually takes 4-6 weeks.
Most of my jewelry is high quality, solid sterling silver. It is specially formulated to resist tarnish, but, like all silver, will tarnish. You can minimize oxidation by storing silver jewelry in a bag or box away from air and heat. Regularly wearing the jewelry can help rub off tarnish. I allow the silver serotonin necklace I wear daily to develop a bit of a patina. It's OK to wear your sterling silver jewelry in the shower.
Your order will come packaged in a cute, recycled paper gift box with a little card explaining what the molecule represents. I tie it with a ribbon, making a pretty package for gifting - no addition wrapping required.

If you are shipping directly to the gift recipient, I'm happy to include a card with your gift message. Just let me know when you order.
